This study evaluated the patterns of smoking cessation at Wave 4 of the Population Assessment of Tobacco and Health (PATH) Study among established cigarette smokers who were also current e-cigarettes users at Wave 3.
We assessed changes in smoking frequency at Wave 4 among established cigarette and e-cigarette users at Wave 3. The demographics of participants were analyzed as well as e-cigarettes device types, number of cigarettes smoked and time from waking up until the first cigarette. Unadjusted and adjusted odds ratios as well as percentage of discontinuing cigarettes use at Wave 4 were calculated for the different categories of dual users.
Among dual users at Wave 3, 13.1% quit cigarette smoking at Wave 4, whereas half discontinued e-cigarette use and maintained exclusive cigarette smoking. Significant differences in the percentage of smoking cessation were observed across demographic groups - dual users with a bachelor's degree were more likely to quit smoking than dual users who did not finish high school (aOR = 3.06, 95% CI: 1.17-8.00) and smokers aged 25-64 years were less likely to quit smoking than those aged 18-24 years (aOR = 0.49, 95% CI: 0.28-0.86 for smokers aged 25-44 years, and aOR = 0.42, 95% CI: 0.20-0.87 for those aged 45-64). Dual users who smoked more than 15 cigarettes per day were significantly less likely to stop smoking (aOR = 0.38, 95% CI: 0.17-0.88).
E-cigarettes have the potential to aid in smoking cessation. Questions remain as to whether dual use of e-cigarettes and cigarettes should be encouraged as a transitional phase on the path to smoking cessation.
本研究评估了在第 3 波调查中同时也是当前电子烟使用者的已确立香烟吸烟者在第 4 波人口烟草与健康评估（PATH）研究中的戒烟模式。
我们评估了在第 3 波调查中同时也是电子烟使用者的已确立香烟吸烟者在第 4 波调查中吸烟频率的变化。分析了参与者的人口统计学特征，以及电子烟设备类型、吸烟量和从醒来到第一支香烟的时间。对于不同类别的双重使用者，计算了未调整和调整后的优势比以及第 4 波调查中停止使用香烟的百分比。
在第 3 波调查中的双重使用者中，有 13.1%在第 4 波调查中停止了吸烟，而有一半的人停止了使用电子烟，继续只使用香烟。在不同的人口统计学群体中，戒烟的百分比存在显著差异 - 拥有学士学位的双重使用者比没有完成高中学业的双重使用者更有可能戒烟（调整后的优势比为 3.06，95%置信区间：1.17-8.00），25-64 岁的吸烟者比 18-24 岁的吸烟者更不可能戒烟（25-44 岁的吸烟者调整后的优势比为 0.49，95%置信区间：0.28-0.86，45-64 岁的吸烟者调整后的优势比为 0.42，95%置信区间：0.20-0.87）。每天吸烟超过 15 支的双重使用者戒烟的可能性显著降低（调整后的优势比为 0.38，95%置信区间：0.17-0.88）。
电子烟有可能帮助戒烟。目前仍存在疑问，即双重使用电子烟和香烟是否应作为戒烟过程中的过渡阶段而被鼓励。
